This gets us back to pre-2.23 behavior of this primop.
Done by inlining the code of `nix::dirOf` from 2.2-maintenance.

These will change in the next commit to fix the silent regression from 2.23
in the handling of multiple subsequent path separators.

Turns out there's a much better API for this that doesn't have the
footguns of the previous method.
isLegalRefName is somewhat of a misnomer, since it's mainly used to
validate user inputs that can be either references, branch names,
psedorefs or tags.

CURL is not very strict about validation of URLs passed to it. We
should reflect this in our handling of URLs that we get from the user
in <nix/fetchurl.nix> or builtins.fetchurl. ValidURL was an attempt to
rectify this, but it turned out to be too strict. The only good way to
resolve this is to pass (in some cases) the user-provided string verbatim
to CURL. Other usages in libfetchers still benefit from using structured
ParsedURL and validation though.
nix store prefetch-file --name foo 'https://cdn.skypack.dev/big.js@^5.2.2'
error: 'https://cdn.skypack.dev/big.js@^5.2.2' is not a valid URL: leftover

This barfed with
error: [json.exception.type_error.302] type must be string, but is array
on `nix build github:malt3/bazel-env#bazel-env` because it has a `exportReferencesGraph` with a value like `["string",...["string"]]`.

Best I can tell this was never supposed to be exposed to the user
and has been this way since 2.19.
2.18 did not expose this file to the user:
nix run nix/2.18-maintenance -- eval --expr "import <nix/derivation-internal.nix>"
error: getting status of '/__corepkgs__/derivation-internal.nix': No such file or directory
Resolve the derivation before creating a building goal, in a context
where we know what output(s) we want. That way we have a chance just to
download the outputs we want.
Fix#13247
